When my iPhone (with update 13.3.1)is linked by Bluetooth, the screen will go dead and restart! And continue to do so, until the BT on the phone is turned off!

I took it to the dealer( Koons Toyota Westminster Md) and showed them the service bulletin!
This all was after 3 other trips beforehand!

They did a hard reboot! Disconnect the battery! But all the presets were still intact!!

And then did a update! However it is not the same update number as this 2020 premium audio..

(my screen doesn't look like the examples soon in others)

The Service Manager advised me that it was the phones problem and there was NOTHING he could do or Toyota would do!

I contacted the GM and he advised to contact Toyota and open a ticket!

This is beyond my wildest thoughts that a $50k vehicle can not be used...

Again is the 2019 premium audio the same as 2020?

Beside the fact that this Toyota sm is a Richard knoggin, should I try another dealer?

Just Google how to reset network on an iPhone. Plenty of links and it's pretty straight forward and simple.

I would also suggest forgetting the 4runner on your phone and erasing personal data on the 4runner itself. After that I would turn the car off and restart the phone. Then connect them together again and see if that might resolve the issue.

Just an idea as I have no idea what you tried before. If you have done all this and still are having issues and the dealership won't help then I'd go to another one and of still nothing I'd contact Toyota directly.

You must be running the latest iOS. First, forget (delete) the 4Runner from the iPhone Bluetooth settings. You must also remove (delete) the iPhone from the 4Runner radio so there are no phones paired. Turn your 4Runner off. Also, you must TURN OFF the Bluetooth on the iPhone until the last step.

Before starting any of this, back up your phone to your iCloud account and/or your PC / MAC via iTunes...

1. Uninstall Apple Music app (Delete the "Music" app).
2. Reset network settings (Settings > General > Reset > Reset Network Settings).
3. Sign out of your (Apple ID) account on your iPhone.
4. Restart the iPhone.
5. Sign in to (Apple ID) account on iPhone again.
6. Reinstall the Apple Music app.
7. Open the Apple Music app, select songs, then select shuffle and let it begin playing the music on the iPhone first to be sure it’s working properly.
8. Start your 4Runner and allow the head unit to fully boot up.
8. Pair the phone with the truck again (turn Bluetooth on, go to audio screen and select add).

This worked! Thanks you!

The dealer did a hard reset on the 4Runner and downloaded the newest version. I tried the phone again and the same problem! The Service MGR told me,nothing he could do or would do and there were no more steps to take..
I contacted Toyota and open a ticket..
